Release notes

This release brings big changes "under the hood", as well as a some visual changes.

The UI has been cleaned up a bit, going back the the original design in many places.
The preferences window has been revamped to include preferences for plugins as well as a more robust UI for general settings.

Along with these and other GUI changes, there were tons of changes under the hood. The entire app was refactored and cleaned up. This ensure that it is easy for other developers to work on BeatBox, makes regressions less likely to happen, speeds up the core, and allows for plugin support among other benefits. For more on this, please see the previous post on the refactor.
